Rep. Tom Lantos, who as a teenager twice escaped from a Nazi-run forced labor camp in Hungary and became the only Holocaust survivor to win a seat in Congress, has died. He was 80.

Spokeswoman Lynne Weil said Lantos, a Californian, died early Monday at the Bethesda Naval Medical Center in suburban Maryland. He was surrounded by his wife, Annette, two daughters, and many of his 18 grandchildren and two great-grandchildren.

Annette Lantos said in a statement that her husband's life was "defined by courage, optimism, and unwavering dedication to his principles and to his family."

Lantos, a Democrat who chaired the House Foreign Affairs Committee, disclosed last month that he had been diagnosed with cancer of the esophagus. He said at the time that he would serve out his 14th term but would not seek re-election in his Northern California district, which takes in the southwest portion of San Francisco and suburbs to the south including Lantos' home of San Mateo.

White House press secretary Dana Perino announced the news of Lantos' death to reporters at a morning briefing.
